[TypeScript] Fix usage of ReactElement when it should be ReactNode

[djhi]

Problem

There are still some prop types that accept ReactElement where they should accept ReactNode

Solution

Switch from ReactElement to ReactNode where it makes sense.

How to test

• Demos should build
• Enterprise Edition should build (but some of its types may require to change to ReactNode too)

Pull Request Overview

This PR improves type safety by replacing overly restrictive ReactElement types with the more appropriate ReactNode type across multiple components. This allows components to accept a broader range of valid React content including strings, numbers, fragments, and null values.

Key changes:

• Updated prop types from ReactElement to ReactNode for props that can accept any renderable content (labels, icons, toolbars, actions, etc.)
• Removed explicit return type annotations where TypeScript can infer the correct type
• Updated JSDoc comments to reflect the new, more flexible types
